Texture Paint is missing in the menu - how do I find it?
Your UI is significantly altered from the default. I noticed one tab labeled “game logic“ and I’m wondering if this is actually leftover UI from an old 2.79 blend file. However, the tab you need might be still there. Hover the mouse over the tab area, and then scroll. If you still don’t see the tab, click the little plus tab at the very end, and you’ll see what you need in the “general“ section of the appearing menu.
